I knew they were getting desperate when they introduced the Borg in Regeneration S2E23(i think). Not only did it ruin all of the history of the Borg so far but the Federation was meant to have no idea who the Borg were yet in Regeneration, the lab boss guy told the junior lab guy to send Star fleet all the information they had straight away. That would mean when Picard and Co ran into them, they would have been on the Enterprise computer already wouldn't they? I think it was a desperate attempt to do what they did at the end of season 3 of Voyager but failed terribly. As a side note, i didnt like when they introduced the Ferengi in season 1 (i think) either. When did you think they had become desperate.
